  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Please refer to "DRIVING METHODS OF LED MODULE".
  5. 5. De-rating may be needed under low input voltages. Please refer to "STATIC CHARACTERISTIC" sections for details.
  6. 6. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
  7. 7. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again.
  8. 8. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
  9. 9. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly  point (or TMP, per DLC), is about 75℃ or less.

FAQ

Can I use the HLG-320H-15B to power dimmable 15V LED lighting in an outdoor parking structure?

Yes. The HLG-320H-15B delivers 285W at 15V with a built-in dimming input accepting 1-10V, PWM, or resistance signals. Its IP67 waterproof rating handles the rain, spray, and dust typical of open-air parking structures, while the dimming capability supports occupancy-based or daylight-harvesting controls.

Is the HLG-320H-15B suitable for dimmable 15V LED tunnel or underpass lighting?

Yes. With 285W output, IP67 waterproofing, and a -40°C to +90°C operating range, the HLG-320H-15B handles the humidity, condensation, and temperature swings common in tunnels. The dimming input allows gradual brightness transitions at tunnel entry and exit zones.

Can the HLG-320H-15B drive 15V LED lighting in a marina or waterfront installation?

Yes. The IP67 waterproof rating provides full dust and temporary immersion protection, making it suitable for marinas, boardwalks, and waterfront installations where saltwater spray and high humidity are present. The 285W at 15V output powers substantial dock or pier lighting arrays.

How many 15V LED fixtures can I connect to the HLG-320H-15B?

The total connected load must not exceed 285W at 15V (19A). For instance, if each 15V fixture draws 40W, you can connect up to seven fixtures (280W total). Always sum the rated wattage of all fixtures and ensure the total remains at or below 285W.

Can the HLG-320H-15B operate in freezing winter conditions?

Yes. The HLG-320H-15B is rated for an operating temperature range of -40°C to +90°C, making it fully capable of continuous operation in sub-zero environments. Its IP67 sealed enclosure also prevents moisture ingress from ice, snow, or condensation.
